关于为什么DNA过渡是第一顺序的评论？强无序聚合物解束缚中的奇异性和Griffiths奇异性
Comment on Why is the DNA Transition First Order? and Griffiths Singularities in Unbinding of Strongly Disordered Polymers
摘要：
论文[1，2]考虑了无序杂聚物的解束缚。他们发现当无序很强（即结合能的比值v很大;在DNA中v约为1.1）时会发生一级相变[1]，否则会发生格里菲斯奇点，即无限级相变[2]。这个问题很重要，因为许多物理现象都映射到同一个模型上（见参考文献1）。在[1，2]中）。无序强度的剧烈非普遍性是意料之外的。不幸的是，这两个标题都是误导性的：他们声称的结果只被证明是均聚物。
英文摘要：
The papers [1,2] consider unbinding of a disordered heteropolymer. They find the first order phase transition [1] when disorder is strong (i.e. the ratio v of the binding energies is large; in DNA v is~1.1) and the Griffiths singularity, i.e. infinite order transition, otherwise [2]. The problem is important, since many physical phenomena map onto the same model (see refs. in [1, 2]). Drastic non-universality in the strength of disorder is unanticipated. Unfortunately, both titles are misleading: they claim the results which are proven for homopolymers only.
